* The maximum power limit specified is for a time limit of 30 minutes. Power greater than the specified limit may be used with care, using a shorter than 30 minute time period to limit temperature rise. Also, the RF current through the coil should be monitored to prevent thermal failure. Recommended maximum temperature rise: 35 dgrees C, maximum core temperature 80 degrees C.
